Why Choose the IMO FMT6/BN-3H Inductive Proximity Sensor?

The IMO FMT6/BN-3H is a heavy-duty M30 full-metal inductive proximity sensor designed for reliable non-contact detection of metallic objects in industrial automation, machinery and process equipment. Part of the IMO FM full-metal sensor range, it features an AISI 316L stainless steel housing and active sensing face for increased mechanical durability in demanding industrial environments.

The FMT6/BN-3H provides an enhanced nominal sensing distance of 10 mm, with an operating distance of 0–8.1 mm. Its shielded M30 construction enables flush mounting into suitable metal surroundings, making it well suited to position sensing, component detection and machine monitoring applications requiring a larger sensing range.

Operating from a 10–30 V DC supply, the sensor provides complementary NPN normally open and normally closed outputs with a load capacity of up to 200 mA. An 80 Hz switching frequency, M12 plug connection, yellow output-state LED and IP67 / IP68 / IP69K protection provide dependable performance across demanding industrial automation applications.

Key Advantages

  • Heavy-duty M30 full-metal inductive proximity sensor for industrial automation.
  • 10 mm enhanced nominal sensing distance for reliable metallic target detection.
  • NPN normally open + normally closed outputs provide flexible control integration.
  • Shielded construction supports flush mounting into suitable surrounding metal.
  • AISI 316L stainless steel housing and active sensing face provide robust mechanical construction.
  • Maximum load current of 200 mA for compatible control circuits.
  • IP67, IP68 and IP69K protection supports demanding industrial installations.
  • M12 plug connection simplifies installation, maintenance and sensor replacement.

Reliable Non-Contact Metal Detection

Inductive proximity sensors such as the IMO FMT6/BN-3H detect metallic targets without requiring physical contact. The sensor generates an electromagnetic field at its active sensing face, and the introduction of a suitable metallic target alters this field, causing the electronic outputs to switch. This non-contact operating principle helps minimise mechanical wear during repetitive machine cycles.

The FMT6/BN-3H combines a generous 10 mm nominal sensing distance with rugged M30 full-metal construction and complementary NPN outputs. Its shielded design supports flush installation, while the AISI 316L stainless steel construction and high ingress protection make it particularly suitable for machinery where durability, contamination resistance and dependable metal detection are important.

Typical Applications

  • Metal component presence detection.
  • Machine position and end-of-travel sensing.
  • Industrial automation and assembly equipment.
  • Conveyor and material handling systems.
  • Production and packaging machinery.
  • Washdown and demanding industrial environments.
  • Heavy machinery and automated handling equipment.
  • Position monitoring of metallic machine components.
  • OEM machinery and automated production systems.
